## About the Role

At Genmab, we are committed to transforming the lives of patients through innovative and differentiated antibody medicines. As our organization continues to grow internationally, we are looking for an experienced and hands-on **Senior HR Systems Consultant – Workday** to join our global HR Systems team.

In this role, you will play a key part in expanding and optimizing our global Workday platform, with a particular focus on deploying Workday in new countries across the European Union.

We are looking for a versatile Workday professional with strong configuration skills, broad functional knowledge across the Workday ecosystem, and proven experience delivering country implementations.

You will be responsible for partnering on designing and configuring the majority of the Workday solution yourself, taking ownership from initial requirements gathering through configuration, testing, go-live, and stabilization. While you will have access to support from internal colleagues and external specialists, we expect you to be comfortable independently managing complex Workday configuration activities and making informed functional design decisions.

You will work closely with HR, Payroll, Finance, IT, and other stakeholders to ensure that our Workday solutions are scalable, compliant, and aligned with both global standards and local European requirements.

## Key Responsibilities

### Workday Country Deployments

– Take hands-on functional ownership of Workday deployments for new EU countries, from requirements gathering and solution design through configuration, testing, go-live, and hypercare.
– Independently perform the majority of Workday configuration required to establish a new country, including organizational structures, staffing models, job profiles, compensation structures, business processes, security, and relevant country-specific settings.
– Configure country-specific Workday functionality, including absence plans, holiday calendars, working schedules, employee classifications, and local business process variations.
– Translate local HR and payroll requirements into practical Workday solutions while maintaining alignment with Genmab’s global configuration standards.
– Identify and address dependencies across Workday modules, business processes, security, reporting, and integrations.
– Work with internal specialists and external partners on areas requiring additional technical or country-specific expertise, including payroll integrations and complex statutory requirements.
– Execute functional and end-to-end testing, troubleshoot configuration issues, and ensure the system is ready for deployment.
– Support data migration, cutover activities, go-live preparation, and post-implementation stabilization.
– Develop reusable configuration approaches and deployment documentation to support efficient future country rollouts.

### Workday Configuration & Functional Expertise

– Serve as a senior, hands-on Workday functional expert with broad knowledge across Core HCM, Compensation, Recruiting, Onboarding, Talent & Performance, Absence, Time Tracking, Reporting, and Security.
– Independently configure and maintain Workday business processes, condition rules, approval workflows, supervisory organizations, security roles, calculated fields, and reporting solutions.
– Understand how Workday modules interact and assess the wider impact of configuration changes across the platform.
– Investigate and resolve complex Workday issues, including those involving multiple modules, business processes, or security configurations.
– Support integrations and data flows between Workday and external systems, working with technical specialists where appropriate.
– Ensure configuration is scalable, maintainable, and consistent with global HR processes and governance requirements.

### Stakeholder Collaboration

– Partner with global and local HR teams to understand business requirements and translate them into Workday configurations.
– Act as a trusted advisor on Workday capabilities, recommending practical and sustainable solutions.
– Facilitate requirements workshops, solution design discussions, and testing activities.
